    <p>I have a small PHP web-based application that is beginning to grow moderately in size.</p> <p>I'm starting to become concerned with managing my PHP code base, given <strong>PHP</strong> is a <strong>loosely/weak typed, dynamic language</strong>.</p> <p>How do others manage their code based for loosely/weak typed, dynamic languages?</p> <p>Do pre-parsers exist for PHP that allow me to runs checks on my code base to identity such things like below?</p> <pre><code>$var1 = 'data'; // vr1 doesn't exist, it's a typo of $var1, but PHP would allow for this and not complain echo $vr1; </code></pre> <p><strong>UPDATE</strong>:</p> <p>The example above might not be the best example but essentially, what I'm trying to convey is that certain errors in a dynamically weak typed language would only be found when the code is run in production at RUN TIME; whereas, some of these issues would typically be found in strongly typed static languages at COMPILE time.</p> <p>How can I also find these non-algorithm type of errors in PHP prior to moving my code into production without having to create an insane number of Unit Tests?</p> <p>As such, does anything exist where I can run my PHP code through it, prior to moving into production, and this pre-processor parses my code to ensure I'm only using defined variables, etc. Essentially, check my code for validation for non-algorithmic type of uses. E.g. not trying perform algebra on a string, etc.</p> <p><strong>UPDATE 2</strong></p> <p>Please note, this question is still <strong>not answered</strong> because I'm looking for a way to identity these type of non-algorithmic errors in PHP at "compile" type, not RUN TIME.</p>

    2. COHonestly PHP is a mess. With includes that can be conditional and these includes themselves can include more files, polluted namespace, and a plethora of other things, it's really hard to know if a variable will be defined or not until runtime.

    3. CO@Null That's really a universal problem among programming languages that can conditionally include files, which happens to be an important feature of PHP. It's the job of the programmer to bring structure into his application.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
